Description

Technical Field

[0001] This utility model relates to the field of rooftop tents, and in particular to a locking mechanism for rooftop tents. Background Technology

[0002] Nowadays, tourism is an activity people engage in to relax, and with the increasing popularity of private cars, self-driving tours have become a new form of tourism. Among these, rooftop tents were developed to meet the convenience needs of people traveling by car. Existing rooftop tents can basically meet daily usage needs, but there are still some shortcomings that need to be improved.

[0003] Most rooftop tents use hinged latches. When a car is driven in the wild, it is often bumpy and jolted up and down, which can easily cause the latches to unlock. This can lead to the rooftop tent lid and base becoming detached, posing a safety hazard. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a locking mechanism for a rooftop tent, which solves the issue of the lock easily unlocking due to vehicle bumps.

[0005] The technical solution adopted by this utility model is: a locking mechanism for a rooftop tent, including a first fixed seat, a second fixed seat, a first rotating plate, and a second rotating plate. The first fixed seat and the second rotating plate are rotatably connected to the first rotating plate. The end of the second rotating plate is provided with a first latching part, and the second fixed seat is provided with a second latching part. When the first latching part and the second latching part are latched, the rotation center of the first rotating plate and the first fixed seat is located between the rotation center of the second rotating plate and the first rotating plate and the first latching part. The device also includes a latching plate, which is slidably connected to the first fixed seat. The first rotating plate is provided with a stop block, and the latching plate is correspondingly provided with a latching block. When the stop block and the latching block are latched, the latching block locks the first rotating plate.

[0006] With the above technical solution, when the user uses the device, they slide the locking plate to disengage the locking block from the stop block, rotate the first rotating plate, and the second rotating plate moves towards the second fixed seat, disengaging the first locking part from the second locking part, thus unlocking the lock. To lock the lock, first engage the first locking part with the second locking part, then rotate the first rotating plate to engage the stop block with the locking block, thus locking the lock. The engagement of the stop block with the locking block prevents the first rotating plate from rotating while the vehicle is in motion, preventing the first locking part from disengaging from the second locking part and avoiding potential safety hazards.

[0007] Furthermore, two of each of the latching blocks and the stop blocks are provided. The two latching blocks are symmetrically arranged on both sides of the latching plate, and the two stop blocks are symmetrically arranged on both sides of the first rotating plate.

[0008] With the above technical solution, the two locking blocks and the two stop blocks are symmetrically arranged, making the locking of the first fixed seat and the first rotating plate more stable.

[0009] Furthermore, it also includes an elastic element connected to the snap-fit ​​plate and the first fixing seat, the elastic element driving the snap-fit ​​block to slide toward the stop block.

[0010] Through the above technical solution, the elastic element exerts force on the snap-fit ​​plate, causing the snap-fit ​​block to be subjected to force in the direction of the stop block, making the locking of the first fixed seat and the first rotating plate more stable, and the snap-fit ​​effect between the stop block and the snap-fit ​​block better.

[0011] Furthermore, the stop block is provided with an inclined surface.

[0012] With the above technical solution, during the locking process, the locking block slides along the inclined surface and finally locks directly with the stop block, making it more convenient to use.

[0013] Furthermore, the snap-fit ​​plate is provided with an extension plate, and the first fixing seat has a strip hole, and the extension plate is slidably connected on the strip hole.

[0014] Through the above technical solution, the extension plate limits the snap-fit ​​plate, preventing the snap-fit ​​plate from sliding out of the strip hole.

[0015] Furthermore, the first fixing base is provided with a positioning hole, and the snap-fit ​​plate is provided with a positioning rod. The positioning rod is always located in the positioning hole, and the positioning rod and the extension plate are respectively located on both sides of the snap-fit ​​plate.

[0016] With the above technical solution, the positioning rod is always slidably connected on the positioning hole, which enables the snap-fit ​​plate to slide stably, limits the snap-fit ​​plate, and facilitates use.

[0017] Furthermore, a lock cylinder is mounted on the first rotating plate. The lock cylinder includes a mounting block and a cam. The cam is rotatably connected to the mounting hole. An avoidance hole is provided on the latching plate. The cam is located in the avoidance hole. When the lock cylinder is locked, the protrusion on the cam limits the latching plate. When the lock cylinder is unlocked, the cam disengages from limiting the latching plate.

[0018] With the above technical solution, when the latch is in the locked state and the protrusion of the cam is facing the extension plate in the clearance hole, the sliding locking plate keeps the locking block engaged with the stop block. When the lock cylinder is unlocked and the protrusion of the cam is not facing the extension plate, the sliding locking plate allows the locking block to disengage from the stop block, resulting in a better locking effect of the latch.

[0030] See Figures 1-3 A locking mechanism for a rooftop tent includes a first fixed base 1, a second fixed base 2, a first rotating plate 3, and a second rotating plate 4. The first fixed base 1 and the second rotating plate 4 are rotatably connected to the first rotating plate 3. The end of the second rotating plate 4 is provided with a first latching part 401, and the second fixed base 2 is provided with a second latching part 201. When the first latching part 401 and the second latching part 201 are latched, the rotation center of the first rotating plate 3 and the first fixed base 1 is located between the rotation center of the second rotating plate 4 and the first rotating plate 3 and the first latching part 401. The mechanism also includes a latching plate 5, which is slidably connected to the first fixed base 1. The first rotating plate 3 is provided with a stop block 301, and the latching plate 5 is correspondingly provided with a latching block 501. When the stop block 301 and the latching block 501 are latched, the latching block 501 locks the first rotating plate 3.

[0031] When in use, the user slides the latching plate 5 to disengage the latching block 501 from the stop block 301, rotates the first rotating plate 3, and moves the second rotating plate 4 toward the second fixed seat 2, disengaging the first latching part 401 from the second latching part 201, thus unlocking the latch. To lock the latch, first latch the first latching part 401 from the second latching part 201, then rotate the first rotating plate 3 to engage the stop block 301 with the latching block 501, thus locking the latch. The engagement of the stop block 301 with the latching block 501 prevents the first rotating plate 3 from rotating while the vehicle is in motion, thus preventing the first latching part 401 from disengaging from the second latching part 201 and avoiding potential safety hazards.

[0032] The rooftop tent consists of a base, a rotating cover, and a tent fabric. The first fixed seat 1 is fixedly connected to the base, and the second fixed seat 2 is rotatably connected to the rotating cover.

[0033] Preferably, the first locking part 401 is a hook, and the second locking part 201 is a round rod.

[0034] See Figures 1-3 Two snap-fit ​​blocks 501 and two stop blocks 301 are provided. The two snap-fit ​​blocks 501 are symmetrically arranged on both sides of the snap-fit ​​plate 5, and the two stop blocks 301 are symmetrically arranged on both sides of the first rotating plate 3.

[0035] The two locking blocks 501 and the two stop blocks 301 are symmetrically arranged to make the locking of the first fixed seat 1 and the first rotating plate 3 more stable.

[0036] See Figure 2 It also includes an elastic element 6, which is connected to the snap-fit ​​plate 5 and the first fixed seat 1. The elastic element 6 drives the snap-fit ​​block 501 to slide toward the stop block 301.

[0037] The elastic element 6 exerts force on the snap-fit ​​plate 5, causing the snap-fit ​​block 501 to be subjected to force in the direction of the stop block 301, making the locking of the first fixed seat 1 and the first rotating plate 3 more stable, and the snap-fit ​​effect between the stop block 301 and the snap-fit ​​block 501 better.

[0038] The preferred elastic element 6 is a spring.

[0039] See Figure 3 The stop block 301 is provided with an inclined surface 3011.

[0040] During the locking process, the latching block 501 passes through the inclined surface 3011, slides along the inclined surface 3011, and finally locks directly with the stop block 301, making it more convenient to use.

[0041] See Figures 1-4 The snap-fit ​​plate 5 is provided with an extension plate 502, and the first fixing seat 1 is provided with a strip hole 101. The extension plate 502 is slidably connected on the strip hole 101.

[0042] The extension plate 502 limits the snap-fit ​​plate 5 to prevent the snap-fit ​​plate 5 from sliding out of the strip hole 101.

[0043] See Figures 2-4 The first fixed base 1 has a positioning hole 102, and the snap-fit ​​plate 5 has a positioning rod 503. The positioning rod 503 is always located in the positioning hole 102. The positioning rod 503 and the extension plate 502 are located on both sides of the snap-fit ​​plate 5, respectively.

[0044] The positioning rod 503 is always slidably connected on the positioning hole 102, so that the snap-fit ​​plate 5 can slide stably, limit the snap-fit ​​plate 5, and facilitate use.

[0045] See Figure 3A lock cylinder 7 is installed on the first rotating plate 3. The lock cylinder 7 includes a mounting block 701 and a cam 702. The cam 702 is rotatably connected to the mounting hole. An avoidance hole 504 is opened on the locking plate 5. The cam 702 is located in the avoidance hole 504. When the lock cylinder 7 is locked, the protrusion on the cam 702 limits the locking plate 5. When the lock cylinder 7 is unlocked, the cam 702 disengages from limiting the locking plate 5.

[0046] When the latch is in the locked state, and the protrusion of the cam 702 is facing the extension plate 502 within the clearance hole 504, the protrusion of the cam 702 abuts against the edge of the clearance hole 504 or leaves a small gap. The sliding locking plate 5 and the locking block 501 are always locked with the stop block 301. When the lock cylinder 7 is unlocked, and the protrusion of the cam 702 is not facing the extension plate 502, the gap between the side of the cam 702 facing the extension plate 502 and the edge of the clearance hole 504 allows the locking plate 5 to slide, so that the locking block 501 can disengage from the stop block 301, and the locking effect of the latch is better.

[0047] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
